| 背面描述 | The reverse presents a portrait of Russian chemist Dmitri Mendeleev, widely credited as the creator of the periodic table, positioned prominently above a stylised arrangement of elemental symbols drawn from the periodic table. The atomic symbols are deliberately selected and organised to spell out the phrase 'One Hundred and Fifty Years', commemorating the 150th anniversary of Mendeleev's publication of the periodic table in 1869. The legend PERIODIC TABLE appears at the top of the field, with the engraver's initials NM present. The design was executed by Natasha Muhl and combines portraiture with typographic ingenuity in a modern commemorative style. |

Tuvalu has functioned as a prolific vehicle for Australian-market commemorative silver since the 1970s, its currency union with Australia giving Perth Mint-produced pieces legal tender status on the island while the real market is entirely collector-driven. This entry in the Periodic Table series was issued to mark the 150th anniversary of Mendeleev's 1869 publication of the first widely recognized periodic table — a moment when he reportedly dreamed the complete arrangement and woke to write it down, though historians of science treat that story with some skepticism.
